"And the illustrious Dharma, the dispenser of all happiness, assuming a human countenance, came out through the right breast of Brahman. And Ahasta (Dharma) hath three excellent sons capable of charming every creature. And they are Sama, Kama, Harsha (Peace, Desire, and Joy). And by their energy they are supporting the worlds. And the wife of Kama is Rati, of Sama is Prapti; and the wife of Harsha is Nanda. And upon them, indeed, are the worlds made to depend.
